Rhian Brewster did eventually come on for Billy Sharp for Sheffield United.

Conor Gallagher is on for Matt Phillips for West Brom.

Loads of substitutions have happened at Bramall Lane too but I can't keep up!

And now a flurry of changes.

Reserve keeper Rúnar Alex Rúnarsson is on for Thomas Partey. Wolves also replace Ruben Neves with Leander Dendoncker too.

Bernd Leno just judges it completely wrong, he makes the right decision by coming out because Adama Traore is in a good position. But the surface catches him out and the speed at which the ball jumps up at him he has no choice but to put his arm out because if he misses it Traore is in and it would be a simple goal for him.

They are checking it on VAR to make sure it was denial of a goalscoring opportunity...

Decision stands. Bernd Leno flaps out at someone on the touchline as he walks off, goes straight through a door at the top of the steps and out of sight.

Mikel Arteta has his head in his hands. It's a shambles.

Arsenal down to NINE men.

OH DEAR.

Bernd Leno comes charging out of his box to try and stop Adama Traore getting on the end of a long ball and he's handled it.

Red. Off. And he's fuming.

Nice from Willian Jose. He makes the most of the space in the middle, cuts in off the left and is invited to shoot from long range with Arsenal's defenders dropping off.

He does but Bernd Leno pats it down then gobbles it up.

The game has changed on it's head - this is what Arsenal were doing to Wolves in the first half. Arsenal are pinned down and hemmed in they can't get out. Yes they're down to ten men, but they're defending so deep.

The press from Wolves is so much better - not letting Arsenal get their heads up when they win the ball back.

It's settled a little at Molineux but 10-man Arsenal are still chasing. Joao Moutinho, the Wolves midfielder who scored the screamer earlier, clashes into Thomas Partey and gives away a free-kick in the Gunners' half.

Billy Sharp fizzes it in from the right. Oli McBurnie tries to get there but it flicks off Kyle Bartley's toe and into Sam Johnstone's arms.

Rhian Brewster is coming on now too.

John Fleck plays a nice ball in behind. It's aimed for Billy Sharp but West Brom get it away.

It's curled back into the box from the left and again, Semi Ajayi is there to put pressure on John Egan, who heads it wide.

Double change for the Baggies.

Hal Robson-Kanu is on for Mbaye Diagne, who has done well today. Callum Robinson is also off. Karlan Grant is his replacement.

Paul Pogba loses his place in the starting line-up virtually at the same time as I received a notification to say he had won Manchester United's latest player of the month award.

Ole Gunnar Solskjaer is searching for the winning formula again. His side have only won one of their last four games in the Premier League, which matches their worst run of the season.

This won't be easy either. Southampton might not be in the best from just now but they have a good record against United.

They have won as many times as they have lost (two) on their last seven Old Trafford visits and it is eight seasons since United last completed a league double against them.

Arsenal need some inspiration, they need something to change. They've actually have a had a good response to the goal - they've tried to hold the width with Bukayo Sakha and Nicolas Pepe and tried to let Emile Smith-Rowe come off as a false 9 without having a number 9. It's causing problems with Conor Coady and Willy Boly because they don't really know whether to step in or not.

David McGoldrick has a hit from long range but it's straight at Sam Johnstone. Easy save.

Huge save from Aaron Ramsdale.

It's a teasing cross from the right and Callum Robinson slides in to poke it goalwards but he's denied from a few yards out.

Turns out he's offside anyway but Ramsdale wasn't to know that.

Vitinha on for Daniel Podence.

Pierre-Emerick Aubameyang on for Nicolas Pepe.
